Hello Shahide043, If All the LED is Flashing Means there is a problem with CPU, CPU is Faulty, If it is under Warranty then Please Contact your Local Siemens with Serial No. (Normally you will find after MLFB no. Starting with S VPXXXXXXXXX) Or Contact Support Request... |

Hello Amit_86, If All the LED is Glow then Try to power On/off the PLC & then See, also During Power off Remove the MMC & Put it Back... Normally upto now I have seen all the LED Flashing means CPU is faulty, But I have not Seen All LED Glows Continuosly..... may be this is new case... |
